Kris - unfortunately I had a little meltdown about 8 months ago
Things were running smoothly. Then one day I came home from work to pack for a redeye trip back East and all my fish looked like absolute hell. They all looked like they were going down the tubes fast, and had looked fine the day before, and the months and yrs leading up. They were all super pale and all dead when I got home 2 days later. If I could tell you what happened I would, but I just have
theories. I can say it didn't openly look like any disease I could ID. Not a coral or invert was any worse for the wear.
Anyway I was pretty distraught

(
Regarding disease - I had (or so I had felt) done my part to ensure the fish were all healthy and super clean going in with all spending between 6 wks to 3 months in my Q tank. I lost my mature A. Chrysopterus pair which really upset me. The angels were damn cool as well (although I couldn't keep a clam). Their nightly spawning routine was awesome.
Not ruling out disease I opted to leave that tank fallow for over 2 months and then anted back up. I've had 2 fish in the 80g tank for the last 6 months. A third fish destined for the 80g is in the Q tank as we speak, but there's no rush, but we're looking at December. I've got some other fish in other tanks, but the 80 gallon tank is an island right now, with plans in 2012 to consolidate animals and systems somewhat.
